Jag drömmer egentligen om att skapa film, men det säger jag inte till någon.
A laser then “draws” every tissue-thin slice of the CAD model on a bed of steel powder, one with the consistency of flour. As the laser passes, the precision machining steel particles are melted and fused to their neighbors, creating steel with the identical mechanical properties as that emerging from the business finish of a steel mill. As every layer is completed, a rubber blade pulls additional materials throughout the in-process part and the laser goes back to work, successively fusing every stage to its predecessor. If you’re looking for some truly sturdy alloys, look no additional than cobalt chrome and Inconel. Protolabs doesn’t machine these supplies, but its 3D printing service is joyful to sinter them for you thru a direct steel laser sintering process.
